From the project

StratoSoar MK3, an autonomous glider meant for high-altitudes, accessible to everyone

TL:DR: The StratoSoar project is a low-cost, lightweight Unmanned Aerial Vehicle (UAV) designed for deployment from a weather balloon at various altitudes, aiming for autonomous and efficient flight to designated GPS coordinates. By offering a more affordable, compact, and lightweight alternative to conventional UAVs, StratoSoar aims to empower educators, researchers, and hobbyists with an accessible platform for exploration and experimentation.

StratoSoar-MK3.0: common questions

What microcontroller does the StratoSoar-MK3.0 use?

The StratoSoar-MK3.0 is built around the ATSAMD21G18A-A, from the Microchip SAM family.

How big is the StratoSoar-MK3.0 PCB?

The StratoSoar-MK3.0 measures 36.6 × 60.3 mm, has 4 copper layers and is 1.0192 mm thick.

How many components are on the StratoSoar-MK3.0?

76 components, from 44 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the StratoSoar-MK3.0 design files?

From the crnicholson/StratoSoar-MK3 repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the StratoSoar-MK3.0 design in my own project?

The repository has no license, so all rights stay with crnicholson. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the StratoSoar-MK3.0 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Microchip SAM firmware against it before you order a PCB.
